Tetraamminecopper $(II)$ nitrate

Vedclass · Answer

(C) $1$. Identify the coordination entity: $[Cu(NH_3)_4]^{2+}$.$2$. The ligand is $NH_3$ (ammine),and there are $4$ of them,so it is 'tetraammine'.$3$. The central metal ion is $Cu$. Let its oxidation state be $x$. $x + 4(0) = +2$,so $x = +2$.$4$. The metal is named 'copper $(II)$'.$5$. The counter ion is $NO_3^-$ (nitrate). Since there are two,it is simply 'nitrate' in the name (the prefix 'di' is not used for the anion in the coordination compound name).$6$. Combining these,the name is 'tetraamminecopper $(II)$ nitrate'.

According to $IUPAC$ nomenclature,the correct name of the compound $[Cu(NH_3)_4](NO_3)_2$ is:
